This study was carried out to provide basic information for standard cultivation guideline of Korean mountain cultivated ginseng (Panax ginseng). Environmental conditions, soil properties, growth process, cultivation methods and sowing timing were investigated in cultivations of Korean mountain cultivated ginseng in Korea (18 region in 9 province). Most of Korean mountain cultivated ginseng was cultivated to north, north-east, east or north-west direction in broad-leaved forest, IV age group, and 500~1,000 trees/ha. Elevation was below 500 m and slope was below $25^{\circ}$ in cultivation. There were significant differences in soil properties by region and cultivation based on organic matter (3.43~24.07%) and pH level (3.8~5.7). Sprouting, leaf unfolding, flowering, fruiting, red ripening, fruit drop and leaf drop of Korean mountain cultivated ginseng was investigated in cultivation. The results show that it took 98 days on average for the whole growth process. There were two methods, sowing and transplant for cultivation. Sowing methods were classified in sowing after opening-testa treatment and direct sowing. and it was 70% and 30%, respectively.

The purpose of this study is to review two books on the history of Korean literature written in Japanese, taking special interest in ancient Korean literature, examining transcultural patterns between the history of North and South Korean literature and that of Japanese literature, and thereby identifying perceptions and description patterns of the history of Korean literature from the perspective of comparative literature. This study analyzes two books with the same title The History of Joseon Literature written in Japanese by Kim Dongwook and Byeon Jaesoo. The two books are not translations of Korean books but were written in Japanese for Japanese and ethnic Korean readers in Japan. The History of Joseon Literature (1974) by Kim Dongwook mainly compares Joseon literature with Japanese literature. The History of Joseon Literature (1985) by Byeon Jaesoo, an ethnic North Korean in Japan, was written from socialistic perspectives. The two books have different standards for evaluating value of the history of Joseon literature and different perceptions about it. Due to the division between North and South Korea, the history of literature is unfolding in different ways in the two Koreas, and the two books reflect such differences. However, they have several common features. For example, they highly regard the value of literature written in Chinese characters and originality of hangga (a folk song of Silla), Hangeul (the Korean alphabet), and pansori (a form of Korean folk music in which a singer accompanied by a supportive drummer sings and chants an epic story). In addition, they both demonstrated that literature written in Hangeul and that written in Chinese characters interacted with each other as the same Korean literature. When the two books were written, the history of Korean literature had been considered a subunit of the history of East Asian or Chinese literature. However, as this study found, Kim and Byeon wrote the two books from a perspective of departing from this view based on nationalism, re-establishing the value of Korean literature, promoting Japanese people's understanding of the high quality of Korean literature, and imbuing ethnic Koreans in Japan with nationalistic pride.

The study is a hypothetical one about how to cut out a single emotion and activate it positively. The study could be used to treat literary therapy through AI. In this study, Hwang Jin-yi's Sijo "Long and Long Night of Winter Solstice Month" was studied. Because this work is very appropriate for the study of emotional cutting and interlinking. This counting method of treatment was used in this Sijo. Hwang Jin-yi's work cuts out "Long and Long Night of Winter Solstice Month" from the beginning. And they dream of regenerating their emotions by putting the time of their cut-off under the 'blanket of the spring breeze.' And in the end, the time of yearning unfolds to infinity, very finely. The extended hours of longing were added to the 'blanket of the spring breeze.' Spread out the times of yearning, it dreams of eternal love, the yearning for everlasting love. These literary acts are expected to lead to many changes in the human nervous system. This is the method of love that dreams of healing emotions in literature. Lover was left but not sent, lover's love amplifies feelings of joy. This method of emotional counting is believed to be very useful in the upcoming literary treatment by AI.

Chosun regime, when it replaced the predecessor of Koryo, had to create political ideological system for new integration of the people. The new system, based on Confucianism, replaced religious values of Buddhism with educational ones. In this educational-ideological system, educational objects were mostly limited in character education's. Its goal was 'restoration of good nature'. For the principal agent of educational process, teacher had the initiative. These traits of educational system can be understood as an 'nature-unfolding perspective' or 'formal discipline perspective'. Moreover, the idea of 'teacher shall be served like prince' seems to be ground of political authoritarianism. In this respects, political traits of traditional education system can be restraining elements for developing independent individuality and free citizenship among Korean people. However, traditional teacher was not only authoritarian trainer. As 'a follower of truth and good', he was equal to his disciples. Teacher learned by teaching them. Students could be colleagues of their teacher. And the main traits of traditional education, focusing character development and community consciousness, are still important, in particular, to modern Korean educational and societal environment wanting in humane and participating citizenship.

The purpose of this study is to examine the characteristics of model of the experiment in students' open inquiry. The research is a reinterpretation of the data collected from the performance of a three-year research project under the theme of 'school science inquiry' the perspective of model of the experiment. The inquiry activities of a focus group made up of four students have been recorded seven times. The recorded files and transcribed copies were analyzed according to interpretive methods. Students' activities were divided into three modeling of the experiment units, considering the modeling unit that includes the process of starting from the problem until it gets solved. The results of the study include illuminating the dynamic process and characteristics of modeling of the experiment and discussing its educational meaning as a distributed cognitive system at each modeling unit. First, students, instruments, and the primitive form of calculation represented by the interaction between them turned out to be important factors in the distributed cognitive system that constitutes model of the experiment. Second, in the early stages, non-verbal activities were carried out in which students became familiar with instruments, and verbal quantitative signs were created when the activities were sufficiently carried out. The generated quantitative signs became a source of data and confidence that can be referenced in subsequent activities. Third, the specialization of instrumentalization occurred, and factors that were important in inquiry, such as variable control, appeared. The results of the study provide new implications for science education research and education, which have been centered on explanatory models, by unfolding the characteristics of model of the experiment that have not been noticed in science education through students' inquiry.

Conventional satellites are generally large satellites that are multi-functional and have high performance. However, small satellites have been gradually drawing attention since the recent development of lightweight and integrated electric, electronic, and optical technologies. As the size and weight of a satellite decrease, the barrier to satellite development is becoming lower due to the cost of manufacture and cheaper launch. However, solar panels are essential for the power supply of satellites but have limitations in miniaturization and weight reduction because they require a large surface area to be efficiently exposed to sunlight. Space solar cells must be manufactured in consideration of various space environments such as spacecraft and environments with solar thermal temperatures. It is necessary to study structural materials for lightweight and high-efficiency solar cells by applying an unfolding mechanism that optimizes the surface-to-volume ratio. Currently, most products are developed and operated as solar cell panels for space applications with a triple-junction structure of InGaP/GaAs/Ge materials for high efficiency. Furthermore, multi-layered junctions have been studied for ultra-high-efficiency solar cells. Flexible thin-film solar cells and organic-inorganic hybrid solar cells are advantageous for material weight reduction and are attracting attention as next-generation solar cells for small satellites.

Plant phenology including flowering, leaf unfolding, and leaf coloring in a forest is important to understand the forest ecosystem. Temperature rise due to recent climate change, however, can lead to plant phenology change as well as snowfall in winter season. Therefore, accurate monitoring of forest environment changes such as plant phenology and snow cover is essential to understand the climate change effect on forest management. These changes can monitor using a digital camera system. This paper introduces the detection methods for plant phenology and snow cover at the mountain region using an unmanned camera system that is a way to monitor the change of forest environment. In this study, the Automatic Mountain Meteorology Stations (AMOS) operated by Korea Forest Service (KFS) were selected as the testbed sites in order to systematize the plant phenology and snow cover detection in complex mountain areas. Multi-directional Internet Protocol (IP) camera system that is a kind of unmanned camera was installed at AMOS located in Seoul, Pyeongchang, Geochang, and Uljin. To detect the forest plant phenology and snow cover, the Red-Green-Blue (RGB) analysis based on the IP camera imagery was developed. The results produced by using image analysis captured from IP camera showed good performance in comparison with in-situ data. This result indicates that the utilization technique of IP camera system can capture the forest environment effectively and can be applied to various forest fields such as secure safety, forest ecosystem and disaster management, forestry, etc.

This paper examines the historical meaning and value of sound art curating as a key type of interdisciplinary and convergence art practice that has been unfolding since the mid-20th century. Accordingly, this paper summarizes the developmental process from the beginning of 'sound art' to the present, but examines the context of visual art in which the material 'sound' functioned in chronological order, and focuses on curating cases of major sound art exhibitions. The purpose of this study is to analyze the impact and contemporary significance of the provided aesthetic experience. To this end, the text is divided into three sections and developed. The first section recognizes that the late 19th century futurist and Dadaist sound poetry, followed by Marcel Duchamp's 1913 attempt to combine musical score with visual art, had a profound influence on the visual music of avant-garde composer John Cage. This explains why this background caused the emergence of exhibitions dealing with 'sound' as a new medium. The second section explains that in the 1970s, sound as an artistic medium played a role in reflecting the critical relationship with the exhibition space dominated by visuality. In the third section, we analyze the curatorial methodology that allows the audience to experience sound as if it were a visual object within the organization of the exhibition hall from the 1980s to the present. Through this process, this paper critically treats the historical practice of customizing the perceptual structure in the exhibition hall, and considers the meaningful methodology of sound art curating considering the role of sound full of vitality in the contemporary art scene.

The purpose of this research was to examine the characteristics of typical Korean grit as opposed to Western conceptualizations. We conducted cluster analysis to identify subgroups based on three related but distinct constructs-passion(harmonious vs. obsessive) and meaning in life. Basic needs satisfaction, life satisfaction, and ego-resilience were further assessed to explore potential group-specific differences in psychological attributes. Highly gritty individuals(n=139; M=22.51 yrs) were selected by using the median. According to our results, gritty individuals were subdivided into 3 groups: the initiative who possesses highly adaptive harmonious passion and meaning in life(35.8%), the obsessive who are high in maladaptive obsessive passion(26.1%), and the passive who are the lowest in all(38.1%). The initiative grit scored the highest in all three attributes while the two other subgroups showed culturally unique patterns. Our results suggest that culture specific factors may mold differently the unfolding and psychological outcomes of grit in Korea.

In this paper, I will study the common point between Korean buddhist thought and Daesoon thought. In 2 chapter, I will illuminate Kang Jeungsan to be familiar with buddhist culture. Daewonsa(大院寺) was the place Kang Jeungsan's to enlighten Path. Kang Jeungsan said Śākyamuni to the people to follow himself. And Kang Jeungsan burned Thousand-Hands Sutra(千手經) as one of Chenjigongsa(天地公事). In 3 chapter I study the unfolding of Korean Maitreya thought and the interpenetration of the three teachings. In 4 chapter I study the idea of Maitreya Buddha and the unity of the three teachings in Daesoon thought. Maitreya has the origin in India. Korea accepted this Maitreya via China. In Silla era, the people accepted Maitreya in relation to Hwarang(花郞). In Unified Silla era, Beopsang jong(法相宗) accepted Maitreya devotion positively and the typical person is Jinpyo(眞表). In Goryeo era, Beopsang jong devoted Maitreya, on the other hand Maitreya devotion changed the popular devotion. In Joseon era, Maitreya devotion changed the popular devotion more and more. In this background, Kang Jeungsan accepted the idea of Maitreya Buddha. And Kang Jeungsan insisted that he is the existence to give Heaven's decree to Choe Jeu(崔濟愚) of Donghak and to combine Jesus of Christianity. The interpenetration of the three teachings is one of the stream of Joseon era's buddhim. We can read this in Hamheo Deuktong(涵虛得通)'s Hyeonjeongron(顯正論) and Yuseokjiluiron (儒釋質疑論) to pretend Hamheo Deuktong and Cheongheo Hyujeong(淸虛休靜)'s Samgagwigam(三家龜鑑). This interpenetration of the three teachings of Joseon era influenced Daesoon thought. The unity of the three teachings in Daesoon thought is divided into three. The first is the unity of the three teachings of Gwanwang(冠旺)'s standpoint, the second is the unity of the three teachings of Sungyo(仙敎) superior standpoint, the third is the unity of the three teachings of Jinmuk(震黙)'s anecdote. The interpenetration of the three teachings of Joseon era is connected with the unity of the three teachings of Jinmuk's anecdote. Thus Joseon era's buddhist thought and Daesoon thought have the common point in the idea of Maitreya Buddha and the interpenetration(unity) of the three teachings.
